This is me at the moment, other than playing with a party, and it works.
As a solo player I have always been at the mercy of my team mates. I'm average, certainly not good enough to turn a game around on my own. My last two matches demonstrate this perfectly...
Both matches on Carrier,
first one, I went 25-7, 4 caps, 7 defends, we lost 170-126
second one, I went 19-5, 2 caps, 6 defends, we won 200-45
For me right now, the harder you try in this game the worse your results. For now I will take the easy option, and build confidence with the maps and weapons slowly. I'm sure others wont like it, but that's just tough I'm afraid.
1: Flank in OBJ modes (Such as dom)
2: Use silenced or even better no weapons (Aka 6 perks and a knife and shocky monkey stick)
3. Dead silence
4. Do not repeat the same set of pathing, Unlike other Cod's you have actually more than 2 options for point of attack on most maps.
That is one option,
The Other is Play a Overwatch position on OBJ maps. Hold down a flag from a vantage point with FMJ Grip and an optic.
People have been chasing red blips Knifing (esp in OBJ modes) can get your kdr up and you can provide benefit for you team by forcing the enemy to watch their back for their OBJ to be taken and defense from flanker knifing numerous people at OBJ B in Dom.
